Abstract
The utility model discloses a release-preventive bypass valve, which comprises a bypass valve body. A motor assembly stator shell connecting portion is arranged at the lower end of the bypass valve body, a release-preventive nut cavity is disposed at the lower end of the bypass valve body, a bypass valve cavity is communicated with the upper portion of the release-preventive nut cavity, a valve spool is mounted in the bypass valve cavity, the diameter of the bypass valve cavity is larger than that of a release-preventive nut, a release-preventive hole is arranged at the bottom of the release-preventive nut cavity, the lower end of the release-preventive nut is fixedly disposed on the release-preventive hole, a release-preventive connecting shaft passes through the release-preventive hole, and the diameter of the release-preventive hole is smaller than that of the release-preventive nut. The valve body of the bypass valve is higher in strength due to the fact that the release-preventive nut cavity is disposed at the lower end of the bypass valve body, and well falling accidents due to breakage of a shell can be effectively prevented.
Description
Technical field
The utility model relates to the drilling equipment field, relates in particular to a kind of bypass valve.
Background technology
As shown in Figure 2, be provided with anticreep pipe nipple 11 between the stator case 10 of common by-pass valve body 1 and motor assembly, be provided with screwed retaining ring chamber 2 in the described anticreep pipe nipple 11, described screwed retaining ring 7 bottoms are provided with anticreep connecting axle 8, the rotor 12 of described anticreep connecting axle 8 and motor assembly is fixedlyed connected, because anticreep pipe nipple 11 housings are thinner, the anticreep pipe nipple ruptures easily, cause motor assembly to fall well, cause drilling failure.
The utility model content
Technical problem to be solved in the utility model provides a kind of anticreep bypass valve that falls the well accident that can prevent effectively that the housing fracture from causing.
For solving the problems of the technologies described above, the technical solution of the utility model is: the anticreep bypass valve, comprise by-pass valve body, the lower end of described by-pass valve body is provided with motor assembly stator case connecting portion, the lower end of described by-pass valve body is provided with the screwed retaining ring chamber, the top in described screwed retaining ring chamber is communicated with the bypass valve pocket, in the described bypass valve pocket spool is installed, the diameter of described bypass valve pocket is greater than the diameter of screwed retaining ring, the bottom in described screwed retaining ring chamber is provided with the anticreep hole that the anticreep connecting axle that sets firmly for the screwed retaining ring bottom passes through, and the diameter in described anticreep hole is less than the diameter of described screwed retaining ring.
Owing to adopted technique scheme, the anticreep bypass valve, comprise by-pass valve body, the lower end of described by-pass valve body is provided with motor assembly stator case connecting portion, the lower end of described by-pass valve body is provided with the screwed retaining ring chamber, the top in described screwed retaining ring chamber is communicated with the bypass valve pocket, in the described bypass valve pocket spool is installed, the diameter of described bypass valve pocket is greater than the diameter of screwed retaining ring, the bottom in described screwed retaining ring chamber is provided with the anticreep hole that the anticreep connecting axle that sets firmly for the screwed retaining ring bottom passes through, and the diameter in described anticreep hole is less than the diameter of described screwed retaining ring; Be provided with the screwed retaining ring chamber in the lower end of by-pass valve body, the valve body of bypass valve has higher intensity, can effectively prevent because housing fracture cause the well accident.

The specific embodiment
As shown in Figure 1, the anticreep bypass valve, comprise by-pass valve body 1, the lower end of described by-pass valve body 1 is provided with motor assembly stator case connecting portion, the lower end of described by-pass valve body 1 is provided with screwed retaining ring chamber 2, the top in described screwed retaining ring chamber 2 is communicated with bypass valve pocket 3, the inwall of described bypass valve pocket 3 is installed with bypass valve pocket 4, in the described bypass valve pocket 3 bypass spool 5 is installed also, be provided with spring 6 between described bypass valve pocket 4 and the described bypass spool 5, the diameter of described bypass valve pocket 3 is greater than the diameter of screwed retaining ring 7, the bottom in described screwed retaining ring chamber 2 is provided with the anticreep hole 9 that the anticreep connecting axle 8 that sets firmly for screwed retaining ring 7 bottoms passes through, and the diameter in described anticreep hole 9 is less than the diameter of described screwed retaining ring 7.
The lower end of described by-pass valve body is connected with the stator case of motor assembly, the upper end of anticreep connecting axle 8 is connected with screwed retaining ring 7, the lower end of described anticreep connecting axle is fixedly connected with the rotor of motor assembly, by-pass valve body has higher intensity, can effectively prevent because anticreep pipe nipple housing fracture cause the well accident, saved anticreep pipe nipple housing simultaneously, simplified the structure.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The utility model is not restricted to the described embodiments, and under the prerequisite that does not break away from the utility model spirit and scope, the various changes and modifications of having done all fall in claimed the utility model scope.
